Circumference = Perimeter
Perimeter of Circle
= 550cm
Also,
Perimeter of Circle
= 2πr
Now,
2πr = 550
πr = 550/2
πr = 275
r = 275/π
r = 275/ 22/7
r = 275 × 7/22
r = 87.5cm

Solve for x. 4(4x-8)^2+16=25
Let's solve your equation step-by-step.
4(4x−8)2+16=25
Step 1: Simplify both sides of the equation.
64x2−256x+272=25
Step 2: Subtract 25 from both sides.
64x2−256x+272−25=25−25
64x2−256x+247=0
Step 3: Factor left side of equation.
(8x−13)(8x−19)=0
Step 4: Set factors equal to 0.
8x−13=0 or 8x−19=0
x=13/8 or x=19/8

Find the value of n: 4/5* n/6=4/5 /n/6
The value of n is ±6.
What is Multiplication?
Multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
The expression is given as,
4/5 × n/6 = 4/5/n/6
Now, Solve the equation as,
4/5 × n/6 = 4/5/n/6
4/5 × n/6 = 4/5 × 6/n
n/6 = 6/n
After cross multiplication,
n² = 36
Taking square root,
n = √36
n = ±6
Hence, The value of n is ±6.

What is the slope of a line parallel to the line whose equation is 6x + 3y = -54
The slope of the line parallel to the line is -2
What are linear equations?Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the slope of the line parallel to the line?The line equation is given as
6x + 3y = -54
Subtract 6x from both sides
3y = -6x - 54
Divide through the equation by 3
So, we have
y = -2x - 17
A linear equation is represented as
y = mx + c
Where m represents the slope
This means that
m = -2
Parallel lines have the same slope
This means that the slope of the line parallel to the line is -2

Nick bought jeans for $34.95 and a shirt for $24.95. The cashier said the total cost including 8.5% sales tax was $68.40. Below are the steps the cashier completed: Step 1: 34.95 + 24.95 = 59.90 Step 2: 59.90 + 8.50 = 68.40 Are the cashier's steps correct? If not, explain the error and then state in complete sentences how to calculate sales tax and total cost correctly. Make sure you give the correct total. (Round the final answer to the nearest hundredth
Answer:
The cashier is wrong
[tex]Amount = 64.99[/tex]
Step-by-step explanation:
Given
[tex]Jeans=34.95[/tex]
[tex]Shirt = 24.95[/tex]
[tex]Sales\ Tax = 8.5\%[/tex]
Solving (a): Is the Cashier's step correct?
The cashier is wrong at step 2 because instead of calculating the sales tax, the cashier add the sales tax percentage to the total cost.
Solving (b):
First, calculate the total cost by adding the cost of jeans and shirt respectively:
[tex]Total = 34.95 + 24.95[/tex]
[tex]Total = 59.90[/tex]
Next, multiply the sales tax percentage to the total cost to get the sales tax amount.
[tex]Sales\ Tax = 8.50\% * 59.90[/tex]
[tex]Sales\ Tax = 5.0915[/tex]
Add the sales tax to the total, this gives the total payable amount.
[tex]Amount = 59.90 + 5.0915[/tex]
[tex]Amount = 64.9915[/tex]
[tex]Amount = 64.99[/tex] approximated

Write the equation in slope-intercept form.
4y + 12x = 16
Answer:
Y = -3x + 4
Step-by-step explanation:
The given equation in slope-intercept form is y = -3x + 4.
Given that, the equation in slope-intercept form is 4y + 12x = 16.
What is the slope intercept form?The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
The standard form of the slope intercept form is y=mx+c.
Here, 4y + 12x = 16
⇒ 4y = -12x + 16
⇒ y = -3x + 4
The slope of an equation is -3.
Therefore, the given equation in slope-intercept form is y = -3x + 4.
